Abstract

A method is implemented by an access gateway to a voice over IP network, connected to a plurality of terminals associated with one and the same telephonic identifier in said network, and comprises, on detection by said gateway of a switch to a connected or disconnected state of a call established between an external terminal and a terminal of said plurality of terminals, transmitting to at least one other terminal of said plurality of terminals a message comprising information relating to said switch of said call to said connected or disconnected state.

Claims

1. A notification method implemented by an access gateway to a voice over IP network, connected to a plurality of terminals associated with one and the same telephonic identifier in said network, said method comprising:

on detection by said gateway of a switch to a connected or disconnected state of a call established between an external terminal and a terminal of said plurality of terminals, transmitting to at least one other terminal said plurality of terminals of a message comprising information relating to said switch of said call to said connected or disconnected state.

2. The notification method as claimed in claim 1, wherein said information comprises at least one parameter indicating said state of said call and a parameter indicating whether said call is an incoming or outgoing call.

6. A non-transitory computer program product comprising instructions for the execution of the steps of the notification method as claimed in claim 1 when said program is executed by a computer processor.

7. A recording medium readable by a computer on which is recorded a non-transitory computer program product comprising instructions for the execution of the steps of the notification method as claimed in claim 1.

3. An access gateway to a voice over IP network, connected to a plurality of terminals associated with one and the same telephonic identifier in said network, said gateway comprising:

a detector for detecting a switch to a connected or disconnected state of a call established between an external terminal and a terminal of said plurality of terminals; and

a transmitter, activated on detection of said switch, for transmitting to at least one other terminal of said plurality of terminals, a message comprising information relating to said switch of said call to said connected or disconnected state.

5. A system comprising;

an access gateway to a voice over IP network as claimed in claim 3, connected to

a plurality of terminals associated with one and the same telephonic identifier in said network, each terminal of said plurality of terminals being suitable for updating a local call journal of this terminal with the aid of information received from said gateway and relating to a switch to a connected or disconnected state of a call established between an external terminal and another terminal of the plurality of terminals.

4. A method for synchronizing a local call journal of a first terminal connected to an access gateway to a voice over IP network, said synchronization method comprising:

on detection by said gateway of a switch to a connected or disconnected state of a call established between an external terminal and a second terminal connected to said gateway and associated with one and the same telephonic identifier in said network as said first terminal, transmitting by said gateway to said first terminal a message comprising information relating to said switch of said call to said connected or disconnected state; and

updating said call journal of said first terminal with the aid of said information.

8. A method for generating a signal in accordance with the V23 protocol specified by the ITU-T, comprising:

generating a message, the signal being suitable for dispatch, by an access gateway to a voice over IP network to a first terminal connected to said gateway, said message comprising at least one parameter representative of a state of connection or of disconnection of a call established between an external terminal and a second terminal connected to said gateway and associated with one and the same telephonic identifier in said network as said first terminal.

9. The method for generating the signal as claimed in claim 8, wherein the message further comprises a parameter indicating whether said call is an incoming or outgoing call.

10. A terminal connectable to an access gateway to a voice over IP network, connected to a plurality of terminals associated with one and the same telephonic identifier in said network, comprising:

a receiver for receiving a message originating from said gateway, said message comprising information relating to the switch of a call established between an external terminal and a terminal of said plurality of terminals, to a connected or disconnected state.

11. The terminal as claimed in claim 10, wherein said message corresponds to the message transported in the signal in accordance with the V23 protocol specified by the ITU-T, comprising a message and suitable for being dispatched, by an access gateway to a voice over IP network to a first terminal connected to said gateway, said message comprising at least one parameter representative of a state of connection or of disconnection of a call established between an external terminal and a second terminal connected to said gateway and associated with one and the same telephonic identifier in said network as said first terminal.

14. The terminal as claimed in claim 10, wherein said message corresponds to the message transported in the signal in accordance with the signaling protocol selected depending on the nature of a port identified by an access gateway at a voice over IP network, comprising a message and suitable for being dispatched, by said gateway to a first terminal connected to said gateway via the port identified, said message comprising at least one parameter representative of a state of connection or of disconnection of a call established between an external terminal and a second terminal connected to said gateway and associated with one and the same telephonic identifier in said network as said first terminal

15. The terminal as claimed in claim 10, wherein said message corresponds to the message transported in the signal, wherein the message comprises a parameter indicating whether said call is an incoming or outgoing call.

12. A method for generating a signal in accordance with the signaling protocol selected depending on the nature of a port identified by an access gateway at a voice over IP network, comprising:

generating a message, the signal being suitable for dispatch, by said gateway to a first terminal connected to said gateway via the port identified, said message comprising at least one parameter representative of a state of connection or of disconnection of a call established between an external terminal and a second terminal connected to said gateway and associated with one and the same telephonic identifier in said network as said first terminal.

13. The method for generating a signal as claimed in claim 12, wherein the message further comprises a parameter indicating whether said call is an incoming or outgoing call.
